High-Speed Transmission and Quality of System for Internet Protocol Broadcasting Services
Byounghee Son, Eui-Seok Nahm, Hagbae Kim · 2008
We introduce both high-speed transmitting and quality of system offering Internet services on the HFC (Hybrid Fiber Coaxial) network with low installation cost. It modulates the phase and the amplitude to the carrier wave signal of the IPBS (Internet Protocol Broadcasting Service) data being acquired from Layer 3 switch. The proposed system is effective to embody the HFC based high speed transmission system. The advantages which are illustrated in this paper are as follows: First, it is capable to transmit the IPBS data with no traffic congestion. Secondly, there is little decreasing the service quality of the existing internet network. Finally, it utilizes the IP-QAM (Internet Protocol-Quadrature Amplitude Modulator) transmitter with more competitive price and the IP-QAM modem.
